Blower first, then cam. Cam made a noticeable difference. You're going to like it. :thumb:

Yer all gonna laugh, but I'm putting together a cam for a 4.8 for a 4x4 truck living at 7,200 ft. 188/ 186 .479- .472 113+ 3. Keep in mind, this is for high elevation DD with stock 706 heads. But always open to recommendations and advice................
